Everything went fine while downloading and updating UAG server with the latest SP2, After reboot i noticed that the DNS64 shows Not healthy under the DirectAccess Monitor/Current Status. This is the same behavior that i faced while installing update 1 Rollup 1 early this year and the workaround to fix it was to disable/enable Direct Access from the UAG 2010 console.
